1.When creating a plan sheet for an essay. 2. Write simple ideas or short cut. 3.The effect may be positive or negative depending on the way planned perhaps the person had written to short of an idea that when they came to make a final copy of the essay they had forgotten their idea. This could also have a positive effect by helping in a brain storm if someone has a short period of time. Hope this helps maybe just give you an idea of what to write. Make sure to have a complete sentence unlike me.
